bottle and adapted to enter the opening to seal it.

, It is an object of. the present invention'to providea containerwithsealing means constructed generally along the line disclosed in saidappli-' cation but with the sealing means disposed externally ofthebottle and integrally therewith and so arranged as to-beremovablypositioned in sealing relation with the opening.

A further object ofthe invention is to provide the container with anopening in a flexible side wall thereof near one end of the containerand to provide the container with an integral broad flexible orresilient tab which outstands from.

said end in line with the opening, the tab having an upstanding sealingrib or member which conforms with the configuration of. the openingandis adapted to fit snugly and removably thereinto to seal the opening,thetab being flexed to permit this disposition ofthe sealing member.

A yet further object is to provide a hot water bottle with a reducedextension at one end having an opening in a flexible wall thereof andhaving a tab outstanding beyond the neck in the line of the opening andprovided with a sealing member adapted to be releasably retained in theopening to seal it.

A yet further object of the invention is the provision of a containerhaving an internal rib which projects from one walltoward the oppositewall in the vicinity of the opening to support the flexible walls in thebody of the container against flexing when the walls in the vicinity ofthe opening are flexed to insert the sealing member in the opening andto remove it therefrom.

Another object-of the invention is the provision of a container asdescribed having an upstanding projection rising from the inner face ofthat wall opposite the opening which can be pressed against the sealingmember to force it out of .the opening.

A further object is generally to improve the construction of containersand sealing members for the openings thereof.

Fig. 3 is a sectional detail taken alongthe me- PATENT OFFiCE dian lineof the bottle and illustrating the sealed condition of the bottle. I

Fig.4is a section taken'along line 4-4 of Fig.1.

The hot water bottle ofthe present invention is a unitary'one-piecemolded flexible rubber construction having the top andloottom broadwalls In and 12, the end walls Hand 16, and a neck l8 projecting fromthe end wall l6 andhaving its end wall 20 and side walls-22 and 24 andtop and bottom walls 26 and 28 formed as cone tinuations of the topand-bottom Walls 18-. and 12 of. the body portion of the bottle. Theto'p;w all 26 of the neck is provided with a circular entrance aperture30 through which the contents of the" bottle are adapted to be passed.On the inner face of the top -wall2 6 of the aperture 30 issur roundedby a downwardly projecting peripherally continuous lip orflange 32 whichpreferably is substantially thicker than the thickness of the top walland is terminated in a flat bottom face 34.- The lip is resilient andcan,be stretched. The end wall 20 of the neck is also preferably thickerthan the top and bottom walls Iii and I2, asillustrated in Figs. 2 and3. I

The bottle is provided with an outwardly projecting flexible andresilient tab 36 which outstands from the end wall 20 of. the necksubstantially in line with the top wall 26 thereof. The tab is disposedin the median line of the bottle opening 30 and is preferably about aswide as i the diameter of said opening. The-tab at or near its-outer endisprovided with a closure member the lip 32 of the opening to snuglyengage the rib entirely. about its periphery, thereby to seal or plugthe opening.

The rib at the top thereof is provided with a spheroidal head 40 havingan outstanding flat faced annular flange 42 which outstands beyondsealing member may be removed from the opening by pressing the bottomwall 28 upwardly against the head 48 and at the same time stretching theneck in the direction of the length of the opening 38, thereby to pressthe head and flange out of the opening. The tab 36 can also be providedat its end with a projecting finger grip 43, see Fig. 3, by which thesealing member can be pulled out of the opening.

The bottom wall preferably is provided with a projection M whichupstands from the inner face thereof under the opening 36 into aposition close under the head it of the closure member when it is in theopening so that the bottomlwall can. be pressed against the head toforce it outofthe opening without excessive compression of the neck 18.The bottom wall 28 preferably has a concavity 5.6 under the projectionadapted to receive the fingers in pressing the projection against thesealing member and also in stretching, the neck to enlarge the openingand facilitate the removal of the sealing member.

The top wall of the bottle is also provided with an integral rib 48which dependsfrom its inner face at or near the junctionof the neck !8with the" body of the bottle and is terminated close to but away fromthe inner face of the bottom .wall l2 to provide a passage 56 thereundertoadmit flow of liquid or other material between thebody and neck. Saidrib 38 preferably is arcuate and concentric with the opening and isrelatively stiff against endwise pressure and serves to hold; the bodyof the container against undue collapseas the neck and sealing member ismanipulated.

I claim: 1.,A molded rubber hot water bottle having topand bottom flatwalls, the top wall having an opening through which the contents of thebottle are adapted to pass, a flexible tab integral with opening and tooverlie and be seated upon said lip, all parts being integrally moldedin one piece and all composed of the same material.

2. .A molded one-piece rubber container having a wall provided withafilling opening, a flexible tab integrally' molded with said wallhaving an upstanding sealing plug insertible in said opening, and asecond wall having a flexible part provided with a plug-removingprojection rising from the inner face of said part under said openingand terminated close under the plug inthe opening.

3. A molded one-piece rubber container having a flexible wall providedwith a filling opening, a. flexible tab integrally molded with said wallhav ing an upstanding sealing plug insertible in said opening, and asecond flexible wall having a plug removing projection rising from theinner face of said wall under said opening and terminated close underthe plug in the (opening, the outer face of said" wall' having adepression under said projection.

4.. A container having a flexible walled body, one wall of which has afilling opening, a sealing plug adapted to be forced into and out ofsaid opening, and a stiff wall-supporting rib projected from one walltoward and terminated adjacent to the opposite Wall near said opening.
